Abstract
DTUs
IPR
portfolio
on
so-‐called
Generalized
Phase
Contrast
(GPC)
covers
a
family
of
powerful
“light-‐engine”
approaches
for
generating
speckle-‐free
contiguous
optical
distributions
using
advanced
spatial
phase
modulation.
GPC
has
been
used
in
applications
such
as
optical
trapping
and
manipulation,
active
microscopy,
structured
illumination,
optical
security,
parallel
laser
marking
trials
and
recently
in
contemporary
biophotonics
applications
such
as
for
real-‐time
parallel
two-‐photon
optogenetics
and
neurophotonics.
Our
most
recent
GPC
light
sculpting
developments
geared
towards
these
applications
will
be
presented.
This
includes
both
a
static
and
a
dynamic
GPC
Light
Shaper
implementation
based
on
our
latest
theoretical
derivations
to
demonstrate
the
benefits
for
typical
applications
where
lasers
have
to
be
actively
shaped
into
particular
light
patterns.
We
then
show
the
potential
of
GPC
for
biomedical
and
multispectral
applications
where
we
experimentally
demonstrate
the
active
light
shaping of
a
supercontinuum
laser
over
most
of
the
visible
wavelength
range.
